Karabakh's war ends in a day. Its Armenian population leaves in a week.

By 30 September, Armenia said 100,480 people had crossed from Nagorno-Karabakh into its territory. The figure, reported by the prime minister's spokesperson, described an exodus on a scale that political assurances from Baku had failed to prevent.

Eleven days earlier, Azerbaijan had launched an offensive against the ethnic Armenian forces governing the enclave. Within about a day, those forces accepted a Russian-mediated ceasefire and agreed to disarm. Azerbaijan's president, Ilham Aliyev, declared that his country's sovereignty had been restored.

The end of organised resistance did not produce confidence among the population expected to live under the returning authorities. Residents left through the Lachin corridor, the route whose restricted access had dominated the humanitarian dispute for months. What diplomats had discussed as a road for supplies became the main route out.

The distinction is now central to Europe's response. Nagorno-Karabakh is internationally recognised as part of Azerbaijan. Recognition of that territorial status does not settle how its residents must be treated, whether they can safely remain or return, or what outside access is needed to verify their protection.

Baku says it will guarantee the rights of ethnic Armenians within Azerbaijan's legal system. Yerevan describes the events as forced displacement and ethnic cleansing. Those positions are not reconciled by the ceasefire. The immediate facts are the defeat of the local armed structures, the departure of most of the population and a humanitarian operation expanding inside Armenia.

The road that changed the terms of the crisis

Before the attack, diplomacy had centred on access. Restrictions along the Lachin corridor separated the enclave from Armenia and constrained supplies. Azerbaijan disputed Armenian descriptions of the situation and promoted access through Aghdam, a route from territory under its control.

The disagreement over roads was also a disagreement over authority. Accepting supplies through Aghdam carried political meaning for people who feared that Baku would use dependence to enforce integration. Insisting on Lachin alone, meanwhile, allowed Azerbaijan to portray the dispute as resistance to its sovereignty. Humanitarian organisations needed delivery arrangements that did not require them to resolve the sovereignty argument.

On 18 September, the International Committee of the Red Cross organised simultaneous deliveries through Lachin and Aghdam. It was a practical opening after prolonged negotiation. The military operation began the next day, showing how little protection a limited agreement over access offered against a decision to use force.

Azerbaijan described its action as a response to security threats and used counter-terrorism language. That is the government's explanation of the operation, not a neutral description that removes the need to examine civilian consequences. Local authorities reported deaths and injuries, while aid organisations prepared medical evacuations.

The ceasefire announced on 20 September required the local forces to lay down their arms. Representatives subsequently met Azerbaijani officials for discussions on reintegration. These talks took place after the military balance had been decisively changed, leaving the Armenian representatives with far less bargaining power than the language of negotiation might suggest.

Aliyev's televised address presented the outcome as the restoration of national authority and offered assurances concerning cultural, religious and other rights. Those promises are relevant to what Baku says it intends. They cannot substitute for evidence of how police, courts and administrators will treat people who have lived for decades outside its effective control.

The exodus accelerated in the following days. UNHCR reported roughly 19,000 arrivals on 26 September, citing Armenia's government. By 28 September, the government was reporting more than 76,000 and announcing an emergency payment. The month-end figure passed 100,000. The sequence conveys the speed of the movement more accurately than a single undated total.

A fuel-depot explosion on 25 September added to the medical emergency as people were trying to leave. It should be treated as a separate incident rather than casually folded into a battlefield casualty total. Hospitals, evacuation teams and families were dealing with overlapping crises whose causes and victims required careful identification.

The immediate task for aid agencies was to find the injured, assist people unable to travel and sustain those on the road. The ICRC's work also involved communication between parties whose political relationship had broken down. Such access depends on consent and practical arrangements; the organisation does not have an armed mandate to compel protection.

Departure figures establish the scale of displacement but do not individually explain every family's decision. Fear, exhaustion, disrupted supplies and uncertainty about future treatment can combine. Nor does the absence of an order directing every resident to leave establish that departure was freely chosen. The conditions in which a choice is made are part of the protection question.

Europe had observers nearby, not a force in Karabakh

The EU condemned Azerbaijan's military escalation on 19 September and called for it to stop. At the UN Security Council, Josep Borrell stressed the need for humanitarian access and credible protection of the local population. These statements identified obligations and priorities after months of European mediation had failed to prevent renewed force.

The Union already had a civilian mission in Armenia, launched in February at Yerevan's request. Its role was to observe and report in Armenian border areas, support human security and contribute to confidence. It was not a peacekeeping force stationed in Nagorno-Karabakh.

That geographic and operational boundary matters. The existence of European observers in the wider region did not mean they could enter the enclave, halt Azerbaijani forces or enforce a settlement. Treating the mission as a security guarantee would misdescribe both what Armenia requested and what EU governments authorised.

Observation can still have value. A reliable account of activity along Armenia's border can reduce uncertainty and make it harder to dismiss incidents as inventions. The mission may also help distinguish developments inside Azerbaijan's internationally recognised territory from pressure across Armenia's recognised frontier. Those are related but legally and strategically different questions.

Russia's peacekeepers occupied a different position, having deployed under the arrangement ending the 2020 war. Their presence did not prevent the September offensive. Moscow helped broker the ceasefire that followed, but mediation after the balance of force changes is different from deterring the change in the first place.

For Armenia, that distinction raises painful questions about reliance on Russia. It does not mean a European replacement is immediately available. Changing a country's security relationships requires decisions about capabilities, access, financing and commitments. A diplomatic statement of support cannot perform all those functions.

The EU's negotiations between Aliyev and Armenian Prime Minister Nikol Pashinyan had sought to advance a wider settlement. The offensive exposes the limit of a process that depends on the participants continuing to believe negotiation serves them better than unilateral action. A meeting can preserve a channel without changing that calculation.

European governments now face pressure to impose costs on Azerbaijan. European Parliament figures called for reconsideration of relations and possible sanctions if the attack did not stop. A parliamentary demand is not an adopted Council measure, and reporting the two as interchangeable would exaggerate the EU's response.

The choice also requires a specific objective. Measures aimed at securing humanitarian access may differ from those intended to deter pressure on Armenia or hold individuals accountable for abuses. A broad condemnation can encompass all three. An effective policy must say which behaviour is being targeted and what change would justify a different response.

Maintaining contact with Baku need not mean accepting every claim it makes. Contact can be used to seek access for independent organisations, information on detainees and practical arrangements for people who wish to leave or return. Its value should be assessed by those results, rather than by the continued appearance of leaders in the same photograph.

Reintegration needs people willing to live with it

Baku has gained control over territory whose Armenian institutions it regarded as illegitimate. That is a military and political achievement for Azerbaijan's government. It does not demonstrate a workable model of coexistence when the community invited to reintegrate is departing in large numbers.

A credible offer of protection would need to be understandable at household level. Residents would require confidence about documents, schooling, language, property, movement and access to justice. A general assurance of equal rights leaves these questions to the administrators who will implement it, and to courts whose impartiality residents may doubt.

Independent access is therefore particularly important. Monitoring can help establish whether people are threatened, whether property is being protected and whether individuals in custody receive lawful treatment. Without access, each new allegation becomes another exchange of official denials and accusations that affected families have little ability to test.

Any future return must be voluntary and safe. A person who has left should not have to choose between losing a home permanently and returning before adequate protection exists. Preserving records of ownership, identity and family relationships can matter long before a political agreement makes return feasible.

The protection of those who remain is an immediate concern of its own. Elderly people, people with disabilities and isolated residents may be less able to reach assistance or communicate their needs. Their small number compared with the exodus does not reduce Azerbaijan's responsibilities towards them.

There is also a risk that the departure of the population will be used to close the file diplomatically. Once a humanitarian response is organised elsewhere, governments may find it easier to discuss reconstruction and bilateral peace without returning to the rights of the displaced. That would turn emergency assistance into an unintended substitute for protection.

The local de facto authorities announced that their institutions would be dissolved by the start of 2024. At September's end, this is an announced political and administrative step, not a reason to assume every consequence is settled. Records, public employment, pensions and the representation of displaced residents do not disappear as practical questions because an institution is scheduled to close.

Nor can the story be reduced to one side's historical suffering. Earlier phases of the conflict displaced Azerbaijanis and produced claims that remain central to Baku's account. Acknowledging those experiences does not lessen the present obligations towards Armenians. Rights to safety, property and lawful treatment do not depend on which population had the stronger position in a previous war.

Armenia's emergency will outlast the border queues

Armenia's government has to receive a large population in a short period while facing domestic anger over the outcome in Karabakh. Emergency registration and payments are the first stage. Housing, healthcare, education and livelihoods will require a longer response that cannot be organised entirely through temporary reception facilities.

The announced payment of 100,000 drams per displaced person provides an immediate form of assistance. Its existence should not be mistaken for a complete estimate of need. Households arrive with different resources, medical conditions and family networks, and a flat payment cannot cover every combination.

European help can be most useful where it strengthens services already used by local residents. Additional school places, medical capacity and housing support can reduce pressure on host communities while assisting newcomers. Separate short-lived systems may be necessary in the emergency, but their transition into regular provision needs planning.

Employment presents both an opportunity and a constraint. People arriving bring professional skills, but they may lack documents, equipment or a home near available work. Recognition of qualifications and access to childcare can determine whether a family becomes self-supporting as much as a general promise of jobs.

The political pressure on Pashinyan is inseparable from these practical tasks. Opponents blame him for the loss of Karabakh; his government must explain the limits of Armenia's military options while demonstrating that displaced people will be supported. Outside partners should judge the response through concrete capacity rather than expecting a government under such pressure to produce immediate reconciliation.

A wider Armenia–Azerbaijan settlement remains possible in principle, but it now has to proceed alongside a profound new loss of trust. Border arrangements, transport links and diplomatic relations may be negotiated between governments. The future of displaced residents requires additional attention because they cannot be represented adequately by a map alone.

The most revealing next developments will be access for independent organisations, treatment of remaining residents and detainees, and the adequacy of support inside Armenia. Baku's military control is no longer seriously in doubt at the month's close. Whether it will be accompanied by a credible protection regime is the question its victory statement cannot answer.
